Title: Process for the manufacture of artificial rubber-like masses
IPC: C08F36/04
Filed: 1930-09-30
Abstract: Diolefines are polymerized in the presence of substances not of salt-like character which are capable of exerting an emulsifying action and in the presence of a quantity of water less than 10 per cent of the hydrocarbon and insufficient to dissolve the emulsifying agent completely and also in the presence of a highly chlorinated aliphatic compound or a colloidal metallic oxide.  The mixture does not form an emulsion.  Suitable emulsifying agents are albumenous compounds, saponin and the like.  The water present may be of acid, neutral, or alkaline reaction, and it may be sufficient to use the materials in an atmospherically moist state. Other substances capable of polymerizing may be added, such as olefine benzenes, unsaturated ketones, acids, esters, nitriles, &c.  In examples (1) butadiene is polymerized at 60 DEG  C. with saponin, trichloracetic acid and water; (2) butadiene and styrene are polymerized with the same substances; (3) butadiene and b -vinyl-tetrahydronaphthalene are polymerized with the same substances; (4) butadiene and styrene are polymerized with air-dry casein (containing 12-13 per cent of water) and trichloracetic acid; the moist casein may be replaced by anhydrous casein and water; (5) butadiene and styrene are polymerized with egg albumen, colloidal pyrolusite, and water.

Patent GB-1219123-A (GB)
Title: Improvements relating to toll systems for road vehicles
Inventor: JAMIESON THOMAS DUNCAN GRAY ER
IPC: G07B15/02
Filed: 1968-01-17
Abstract: 1,219,123. Toll system for road vehicles FERRANTI Ltd. 15 Jan., 1969 [17 Jan. 1968], No. 2452/68. Headings G4T and G4Q' A toll system for road vehicles comprises a toll point for each vehicle lane, there being a sensor 11 in the road which, on passage of a vehicle causes an interrogator station to emit a signal, which signal is received by transponder (Fig. 2) on the vehicle, debits a prepaid credit unit, and sends a reply signal to the interrogator. If the vehicle has no credit or no transponder, no reply signal is sent and a cine camera 27 is actuated which records the rear number-plate. The sensor utilizes pressure, photo-electric or magneto-electric sensing and the signal may be radio, infra-red or photoelectrical. The passage of the front wheels of a vehicle over pad 11 emits a pulse which causes gate generator 12 to generate a gating pulse, e.g. of 25 ms., and which also activates transmitter 13 to emit a signal at frequency f1 through antenna 15 and also activates receiver 16. If the vehicle has a transponder, the signal is received by receiver 42 and passed through modulator 44 and AND gate 45. The other input of the AND gate is connected to a credit store (pulse counter) 51 which only emits a signal if the store has credit. It is intended that this credit store be officially credited at some chosen time interval and is secured in the transponder by lockable leads. If the vehicle has credit, one or more units are debited from the store and transmitter 46 sends the reply signal at frequency f2 which is received by receiver 16. The interrogator includes a logic network 21 including a 2-stage binary counter 22, an inhibit gate 23 and AND gates 25, 26, gate 26 being opened when the counter holds number 3 (i.e. 2<SP>0</SP>+2<SP>1</SP>=3). Counter 22 normally holds 1, the gating pulse from 12 sets it to 2, but a signal received from receiver 16 resets the counter and returns it to zero. The rear wheels of the vehicle (which have no transponder) set the counter back to 1. If, however, the vehicle emits no reply signal (i.e. no credit or transponder) the rear axle wheels set the counter to 3, gate 25 opens and camera 27 is fired for a few seconds to record the numberplate. Gate 26 opening, inhibits gate 23 and thus keeps the counter at 3 until receiver 16 again receives a signal. Thus the next vehicle which appears will activate the camera regardless of whether it is in credit or not. This waste of film may be prevented by a modification (Fig. 5, not shown) which resets the counter after each camera operation by means of a differentiator and a buffer stage. In an alternative embodiment the signals f1 and f2 are the same frequency in which case a delay circuit is provided for the receiver 16. A higher rate may be set for peak periods by installng a second interrogator station which only operates during these periods. In an alternative credit store, the credit may be added instead of subtracted.

Title: Improvements relating to heat-exchange tubes
IPC: F23M5/08
Filed: 1929-01-24
Abstract: 328,557. Imray, O. Y., (International Combustion Engineering Corporation). Jan. 24, 1929. Moulds.-In casting extensions on a tube this is preheated to welding temperature and the molten metal is caused to overflow from the mould for some time to heat the tube. A seamless wrought steel tube 11, Fig. 6, is placed in a sand mould, 32, 33 having a recess 34, a broad gate 35, an overflow 39, and strengthener 37, and is heated by a burner 45, Fig. 7, to about 800‹ to 900‹ F. Grev cast iron at 2900‹ F., sufficient to fill four moulds, is then poured in, rapidly at first then slowly, the excess metal flowing out at 39. The mould may be arranged to cast a number of or all the extensions on a tube simultaneously as shown in Fig. 7, the cavities 34 preferably being formed by dividing a long cavity by baked sections 43 or alternate extensions may be cast first and, subsequently, others between them. In another modification the mould consists of hard baked sections 53, Fig. 8, separated by sand coated metal or silicon carbide plates and supported in a box 51 by sand 52. In this case the gate 56 is arranged with its large dimension vertical and the overflow metal passes through a cavity 60 arranged to heat the opposite side of the tube and prevent distortion without adhering.

Title: Improved treatment of cellulose fibres and the like
IPC: D06M15/423
Filed: 1935-01-25
Abstract: Cellulosic fibres are given a resistance to creasing by soaking in a solution or emulsion of a wax or product resembling wax, and are then impregnated with a solution of a resin or of substances which are to be condensed to form a resin.  In a modification, the fibres are impregnated with the solution or emulsion of wax and often drying are treated with formaldelyde vapour at a raised temperature.  As waxes there may be used natural or artificial waxes or substances resembling waxes, such as Japan wax and the material prepared according to Specification 305,552, [Class 91]. In an example, the goods are saturated with an emulsion of Japan wax and the sodium salt of oleic acid N-methyl-tauride, pressed, introduced into a solution of dimethylol-urea, and mono- and di-sodium phosphate, dried, and heated.  In another example the emulsion used comprises the wax described in Specification 305,552 and triethanolamine.  In a third example, the materials are treated with a wax as in the first example, with addition of mono- and di-sodium phosphate, dried, and heated with formaldehyde under pressure.

Title: Improvements in or relating to electric indicating or repeating instruments
IPC: G05D3/12
Filed: 1944-02-11
Abstract: 575,301. Remote control systems. SMITH & SONS (ENGLAND), Ltd., S. (formerly SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. Feb. 11, 1944, No. 2604. [Class 40 (i)] In a remote indication system comprising a transmitter and receiver in the form of rotary transformers coupled to a common supply, relative displacement of their rotors produces a phase difference between their output voltages which is used to control a rotating field motor which drives the receiver rotor to a position of zero displacement through reduction gear, to eliminate friction error. As shown in Fig. 1, the output from the rotor slip rings of transmitter 12 is applied to one winding of a two-phase induction motor 21 and the output from the rotor of the receiver 15 applied to the other, the motor driving the receiver rotor through gear train 22 to overcome errors due to friction in the receiver rotor bearings. The outputs of the rotors may be fed in the same sense to the primary windings of one transformer and in the opposite sense to a second transformer, the two phases of the motor being connected to the two secondary windings so that they receive voltages equal to the sum and difference respectively of the rotor outputs. In a modification, Fig. 3, one phase of motor 22 is fed continuously from the mains, while the other is supplied with a quadrature voltage controlled by reversing relay 33, which is actuated by the phase difference of the outputs of the two rotors, in order to drive the motor in one direction or the other. Since the relay 33 may return to its neutral position before the re-alignment is quite complete, a second transmitter and receiver, Fig. 4 (not shown), may be coupled to the first through a gear train, so that they have a larger angular displacement and if relay 33 opens alignment is completed on low gear by means of a second relay. Specification 514,886 is referred to.

Abstract: 469,770. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and FALLOON, S. W. H. W. Feb. 3, 1936, No. 3272. [Class 40 (v)] [Also in Group XXXVI] Phase - differences between voltages are measured by applying the voltages to two circuits normally tuned to a working frequency, each circuit including a variable reactance controlled by a common movement so that the two circuits are detuned equally and in the opposite sense. The voltages set up are combined in a mixing circuit, zero indication being given if the applied voltages are in phase and of equal amplitude. The amount of detuning control necessary to produce a zero reading is a measure of the phase-difference. The voltages may be those in the aerials of a direction finder, and they are applied to tuned circuits 2 ... 5, 2<1> ... 5<1> the detuning capacitances 5, 51 being gang-controlled at 6. The outputs of the two tuned circuits are connected to four valves, the anodes being cross-connected, 1A to 2A<1> and 2A to 1A<1>, the output circuit AL, AL<1> being shunted by a circuit 7 tuned to the working frequency. Amplitude controlling means may be employed in the mixing circuit or in connection with the valves. In the former case for example, the anodes of the valves may be connected through the stator coils of a goniometer and the search coil, forming the tuned circuit 7, rotated.
